Should individual letters be preceded with "an"?

I was reading a comic book and I noticed that the author used "an A" and "an N" in a particular phrase (screenshot below). While I understand the usage of "An A" here (A being a vowel and what not) and "N" having a pronunciation which has a sound similar to "A".

Since most of English alphabets have pronunciations which start with a syllable similar to one of the vowels or semi-vowels; is it OK to prefix the letters using "An"?

For eg. An X, or An Y.

3I would say that "Y" has a pronunciation starting with /wī/ (consonant) and will be prefixed by "a". – Jerry – 2013-05-24T16:22:35.273

Have a read of our blog article on the subject.

The a/an rule is based solely on pronunciation, not the actual letter that follows.

So it's…

  • An eye for an eye
  • An LSD drug user

But note:

  • An honorable death
  • An honest answer
  • but… A human reaction

(don't get me started on an hotel)

So, yes… your example would be written out:

an 'A'.

+1 purely for *don't get me started on an hotel*. Though I think battle isn't really joined until we get to an/a historic

Robert Cartaino and kiamlaluno have answered your question, but since there are only twenty-six letters, I thought I'd try to illustrate the point by typing up a pair of lists.

The following letters begin with vowel sounds:

an A
an E
an F
an H
an I
an L
an M
an N
an O
an R
an S
an X

The following letters do not:

a B
a C
a D
a G
a J
a K
a P
a Q
a T
a U
a V
a W
a Y
a Z

(I believe the letter H has a variant pronunciation, but I'm ignoring that in these lists.)

As you can see, "most" is inaccurate here. Roughly half of the letters have names beginning with vowels.

It's worth pointing out that several letters have phonetic spellings listed in the dictionary, such as ef, kay, wye, and zee. When spelled out that way, I think most letters would follow the "use an before a vowel" rule of thumb, including "an N" (en) and "an H" (aitch). We use the article that matches the phonetics.

1@J.R. Yes, that's right. That's why I said "begin with a vowel sound" and "do not [begin with a vowel sound]". Spelling is irrelevant. – snailplane – 2013-05-24T20:31:14.313

I'm not sure I'd call it "irrelevant" – I thought the phonetic spellings were helpful and a bit instructive in gaining a full understanding of when to use a or an in such cases. You could extend that – it's the same reason why we say "a zero, a one, but an eight." You and I are in hearty agreement on the main issue, I think. – J.R. – 2013-05-25T11:48:18.047

You use an for words starting with vowel sounds, and a for words starting with a consonant sound.

So, it's:

  • An X (/eks/)
  • A U (/juː/)
  • A NASA employee (NASA is pronounced /ˈnæsə/)
  • An FM radio (FM is pronounced /ef em/)

Taking a cue from @snailplane, I thought I would spell out the names and pronunciations (in IPA) of all the letters of the English alphabet.

Letters beginning with a vowel sound, and so would preceded by an:

an A, the letter a, pronounced /eɪ/, beginning with the vowel /eɪ/
an E, the letter e, pronounced /iː/, beginning with the vowel /iː/
an F, the letter ef, pronounced /ɛf/, beginning with the vowel /ɛ/
an H, the letter aitch, pronounced /eɪtʃ/, beginning with the vowel /eɪ/
an I, the letter i, pronounced /aɪ/, beginning with the vowel /aɪ/
an L, the letter el, pronounced /ɛl/, beginning with the vowel /ɛ/
an M, the letter em, pronounced /ɛm/, beginning with the vowel /ɛ/
an N, the letter en, pronounced /ɛn/, beginning with the vowel /ɛ/
an O, the letter o, pronounced /oʊ/, beginning with the vowel /oʊ/
an R, the letter ar, pronounced /ɑr/, beginning with the vowel /ɑ/
an S, the letter ess, pronounced /ɛs/, beginning with the vowel /ɛ/
an X, the letter ex, pronounced /ɛks/, beginning with the vowel /ɛ/

Letters beginning with a consonant sound, and so would preceded by a:

a B, the letter bee, pronounced /biː/, beginning with the consonant /b/
a C, the letter cee, pronounced /siː/, beginning with the consonant /c/
a D, the letter dee, pronounced /diː/, beginning with the consonant /d/
a G, the letter gee, pronounced /dʒiː/, beginning with the consonant /dʒ/
a J, the letter jay, pronounced /dʒeɪ/, beginning with the consonant /dʒ/
a K, the letter kay, pronounced /keɪ/, beginning with the consonant /k/
a P, the letter pee, pronounced /piː/, beginning with the consonant /p/
a Q, the letter cue, pronounced /kjuː/, beginning with the consonant /k/
a T, the letter tee, pronounced /tiː/, beginning with the consonant /t/
a U, the letter u, pronounced /juː/, beginning with the consonant /j/
a V, the letter vee, pronounced /viː/, beginning with the consonant /v/
a W, the letter double-u, pronounced /ˈdʌbəljuː/, beginning with the consonant /d/
a Y, the letter wye, pronounced /waɪ/, beginning with the consonant /w/
a Z, the letter zee, pronounced /ziː/, beginning with the consonant /z/

4a Z, the letter zee, pronounced /ziː/ - If you're American, that is. – fNek – 2014-06-01T12:45:44.823
